Stephanie's Cancer Treatment

My beautiful sister Stephanie was diagnosed with breast cancer, preliminary CT scans show she is positive for metastatic disease to her liver, lung, and bone, placing her in Stage 4. She is the mother of two children, Ethney age 7, and Killian age 4. As the primary income earner for her family, concerns are present because cancer is expensive, and while insurance should cover treatment costs, it does not cover co-pays, missed time from work, and general living expenses. Any support you can provide will be helpful.
